python-pptx - 更改自动形状边框颜色

Question

我正在尝试为我创建的矩形自动形状的边框添加颜色，如下所示。默认颜色似乎是蓝色，但我不确定如何将其修改为自定义颜色。

shapes = slide.shapes
left = top = width = height = Inches(1.0)
shape = shapes.add_shape(
MSO_SHAPE.ROUNDED_RECTANGLE, left, top, width, height)

fill = shape.fill
fill.solid()
fill.fore_color.rgb = RGBColor(255, 255, 255)

slide.shapes._spTree.remove(shape._element)
slide.shapes._spTree.insert(2, shape._element)

Answer 1

弄清楚如何使用以下方法更改自动形状边框颜色：

line = shape.line
line.color.rgb = RGBColor(255, 0, 0)
